St. James's Park: Ross'sling Refreshments
More synchronised sippers in large.
We went to see whether we could see the black swan cygnets, but they weren't anywhere obvious, so we spent some time with the Ross'sling and its parents. They were looking particularly lovely rustling (Ross'tling?) through and amongst the autumn leaves, and showing off their curvy forms individually, in alignment, and echoing each other.
